To all whom it may concern: Be it known that I, THOMAS F. PAYNE, ofPittsbur 1n the countyof'Allegheny and State of ennsylvania, haveinvented a cer-' tain new and. useful Improvement 1n Flushing-Valveaofwhich the following is a full, clear, and. ezia'et description,reference being had to theaccompanying drawings, forming part of thisspecification, in which- Figure 1 is a rear elevation of a valveillustrating my invention; Fig. 2 is a side elevation, partly in sectionFig. 8 is a vertical section showing the valve in its lowered position;Fig. 4% is a vertical section showing the valve in its raisedpos1tion;'F1g. 51s a' is a section on the line 1313 of Fig. 9; and

14 is aseetion on the line14-14 of Fig. 12.

Heretofore influshing valves for'water- "closets of that class in whichthe bowl is flushed by the direct iiow of water" from the main, and iscontrolled by the filling of the valve chamber, the aperture-whichpermits the flow of water to the upper face of the valve, to create aclosing pressure, is minute and, apt to be clogged by foreign matterwhich may besuspended in the water, Whereby the operation of the valveis often interrupted requirin the valve to be taken apart and cleaned.nether diiliculty has been found in-closing the valve where pressure inthe waterinain is insufficient or becomes low, which allows the water topass through the I valve without power to close the same. An-

Eli

other difliculty has been found in the neces sity of taking the valveapart in order to adjust it to the amount of'water to be deliveredto thebowl, or the length of time it is desired the valve shall remain open.

" The object of my invention is to obviate these objectionable features,and it consists in a valve having devices for causing a reverse flow ofwater through the filling a erture whereby the same is continually wased out and kept clean, in devices for creating a partial vacuum in] rearof the operating. iston, and in devices for ad ust1ng'the vaSpecification of Letters Patent.

and it also consists in devices and features of construction heremaftermore fully set forth.

others skilled in the art may employ the same.

In the drawing, 2 represents the threaded socket or inlet adaptedtocommunicate with 5 the water main, and 3 and 3 represent the 6,5.

valve chamber, the upper portion 3 of which is of greater area in crosssection thanflthe' I lower-portion 3*. At the lower portionof 1 5 thevalve chamber 3* isthe valve-seat, 4. 'Sit uate in the valve chamber isa piston valve: having an upper piston head 5 located in the upperportion 3 of the valve chamber and a lower piston head 6 and a valve 7located, in the lower portion 3* of the valve chamber.

The piston heads 5' and 6 are provided with 5 washers or packing 5 and6* which fit.

tightly against the walls of that portion of the valve chamber in whichthey are respec tively located. I The valve 7 is providedwith a washer 7adapted to close the water-way 30 ofthe valve-seat 4. The piston-heads 5and i 6 and the valve 7 are mounted on the stern 8.

The valve chamber 3* communicates by the passages 9 with the pipe 10that leads to the bowl. This pipe 10 is shut off by the parti 7 tion 11-from direct communication with the inlet 2'. Leading from the inlet 2 isan inlet by-pass 12, which at its other endcornmnnifl cates with theport 13 of the plug 14; of the cook 15, the passage of communication be.tween the passage 12 and the port 13' being." minute, although thepassage 1 and thepoit 13 are ofmuch larger area. In the bushihm'unica-tee with the outlet by-pass18 thatt leads to the passage 9. Theplug 14 is v-ided with a central cavity 19 that coin nui sageh2O whichleads to and opens into-the op- 7 per portion of the valve-chamber 3abovethe piston head 5. Theplug 14: is provided with a lever arm 21having a slot in which isle 24 which is supported by the spring 25 lathecasing'26. At the top of the casing 26 isa 1 I will now describe myinvention so that 6 the tinfe oiii 1.9.

eterthan the valve casing, which plug serves to choke the flow ofwaterbefore the valve closes and yet permits the bowl to refill at the closeof the flushing action.

In Figs. 7 and 8 I show a modification in which the push button 24 isarranged horizontally, connected with the lever 21?, and is adapted toextend through va wall.

In Figs. 9,'10, 11, 12, 13, and 14 I show a modification in which theplug 14" and the push button 24 are placed on top of the valve casinginstead or at the side thereof. In this modification the connection withthe water main pipe is at 2 and the pipe leading to the bowl is at 10The piston valve hav- 'ing the heads 5 and 6? and the valve '7 b are ofdilferent shape and the location of the parts is different from thatshown in the other figures. In this modification the cavity 19 and portcommunicate directly with the valve chamber 3*.

t In .my improved valve or metric flush the parts are normally in theposition shown in Figs. 1, 2, and 3, there being a minute openingbetween the passages .12 and 13 which allows water to flow from theinlet 2 through the passage 20 to therupper portion 3 of the valvechamber where itexerts downward pressure against the piston head 5,which is of greater area than the lower face of the valve 7 againstwhich the water from the inlet 2 exerts an upward pressure. Thisdownward pressure therefore normally keeps the valve 7 closed againstits seat 4 and prevents water from flowing to the bowl. Then the pushbutton 24 is. pressed downwardly against the force of the spring 20, thelever 21 gives apartial rotation to the plug 14 I which carries the port13 from the inlet pas sage 12' to and into communication with the outletport 17 and passage 18.- This shuts off the water communication betweenthe inlet 2 I and the chamber 3 and opens a free passage to the bowl,thus flushing thecloset.

between the chamber? and the passage 18 against which is merelyatmospheric pres-. sure. The pressure of'the water below the valve 7thereupon becomes greater than the pressure on the piston head 5 and thevalve 7 is forced upwardin the chamber 3 causing the water in thechamber 3 to be forced out through the passag'es'20, 19, 17 and 18, andpermits the water from the inlet 2 to flow in volume through thepassages 9 and pipe 10 packing of the piston head .6 fitting closely inthe chamber. 3 serves to'keep the pressure of the water in the-main frombeing exerted against the lower side of the piston head 5.

WV'hen it is desired to stop the flow of.

water through the'pipe 10, the push button 24 is released and the spring25 carries it and the lever 21 back to their normal positions and turnsthe plug 14,.bringingthe port 13 out of communication with the passage18 and again in such partial register The inlet and in another with thepassage 12 as to forma minute opening between the passage 12. and theport '13, which again permits the water from the. inlet 2 to flowthrough the passages 12,

. 13,19, and 20'into the chamber 3, and there to gradually close thevalve 7 under the greater pressure above' the piston head 5 than existsbelow the piston head 6. During this slow closing movement the watercontinues to flow in volume to the pip'elO until the plug 27 enters thecontracted .portion of the valve casing below the valve seat and chokesthe flow of water, permit-v ting only sufiicient water to passthe valveas is necessaryto refill the bowl. As the cross area of the chamber 3 isgreaterthan the cross area 01"" the chamber 3 the upwa'rd movement ofthe piston heads 5 and 6 creates a partial vacuum behind. the pistonhead 5 which aids in the return movement of the same.

The advantages of my invention result from the construction which causesthe out? flow of water from the valve chamber to pass through the inletport in a reverse direction keeping this passage at all times clean andfree from obstructions that would interfere. with the operation of thevalve; also from the devices which enable a small pressure of water toclosethe valve; and from devices outside of the valve and by means ofwhich the time occupied in the closing of the valve may be regulated.

Many modifications in addition to those shown in the drawings maybemade'in the. form and location of the parts without departing from myinvention.

Alt ough I have shown my invention applied o a valve for flushingwater-closets, I do not desire to-limit it to this use.

- Having thus described my invention, what I claim' and desire 'tosecure by Letters Patent is 1. Ina flushing valve, the'combinationof avalve chamber havinganimperforate side therein, a passage leading to thevalve chamber, an inlet, an outlet, and a plug having acavity-registering in .all positions with said passage, and said cavityhaving a portar-' ranged in one position to partially uncover the inlet.and in another position to com pletely open the outlet.
